Abstract

A granulate detergent product comprising coated granules which comprise a functional core which comprises one or more detersive agents selected from surfactants and detergency builders, the coated granules further comprising up to 10% by weight of a coating which comprises encapsulated perfume.

Description

Detergent granules and its preparation method
Technical field
The present invention relates to comprise the granular detergent composition of packed spices.
Background of invention
It is known that spices is introduced granular detergent composition with so-called " microcapsule " form.A form known of microcapsule is made up of the trimeric cyanamide-urea-formaldehyde microcapsule with spices nuclear.Present high bulk density detergent granules is usually by the multiviscosisty preparation of mechanically mixing and tensio-active agent and other component (generally including washing auxiliary detergent) and get, thus the formation finished product or prepare one or more other compositions may be to the pre-granulating concentrated additive of feed (post-dosed) thereafter.Yet, found that by this way perfume microcapsule is introduced the material of reuniting causes multiple shortcoming, for example Zhuo Lie dispersibility, have mechanical loss subsequently, unwanted resistates and product invalid (from the viewpoint of perfume delivery).
The dried adding of microcapsule often causes capsular loose reunion, and this is difficult to be distributed in the whole composition under the situation of not using remarkable shearing force, causes significant subsequently perfume loss.
Another alternative route that microcapsule is added drop-wise on the rest part of the composition on the transport unit also often causes unwanted gathering to form.
The solution of this problem at present is the spices introducing slurry by will be packed, and slurry is sparged on Powdered (preferably granulated in advance) composition, and said composition comprises one or more conventional ingredients of detergent composition.This has caused so-called " stratified " detergent granules, and this particle comprises the function nuclear and the skin that comprises packed spices of conventional detergent ingredients.
The what is called of detergent granules " layering " is well-known in the art, normally in the terminal stage of the non-spraying drying machinery pelletization of washing composition, add under the situation of " layering agent " (being generally aluminosilicate), for example " Surfactants in Consumer Products ", Springer Verlag, 1987, described in the 411-413 page or leaf.This is normally for particle size distribution in the flowing property of improving product and/or the control aggregation procedure.
The invention definition
First aspect present invention provides granular detergent products, it comprises the particle through applying that has comprised function nuclear, this function nuclear comprises that one or more are selected from the decontamination reagent of tensio-active agent and washing auxiliary detergent, this particle through applying further comprises the coating of 10wt% at the most, and this coating comprises packed spices.
Second aspect present invention provides granular detergent products, wherein at least 10% of the particle total amount is the particle through applying that comprises function nuclear, this function nuclear comprises that one or more are selected from the decontamination reagent of tensio-active agent and washing auxiliary detergent, and this coating comprises packed spices.
Third aspect present invention provides the method for preparing granular detergent products, and this method comprises:
(i) provide Powdered and/or the particulate state cleansing composition, composition comprises that one or more are selected from the decontamination reagent of tensio-active agent and/or washing auxiliary detergent;
(ii) preparation comprises the slurry of water and packed spices;
(iii) spray this cleansing composition to form particle through applying with described slurry.
Present method products obtained therefrom can, for example, meet the requirement of the present invention first and/or second aspect.
Obscure for avoiding any, should understand the term granular detergent products and contain the Betengent product that is used to clean and/or does washing conditioning.Therefore, the term decontamination reagent that adopts in all aspects of the invention is also contained softener material.Therefore, for all aspects of the invention, decontamination reagent can be selected from tensio-active agent, softener material and/or washing auxiliary detergent.
Detailed Description Of The Invention
For avoiding any doubt, the term " particle " that is used for the object of the invention refers to comprise the particle of a lot of compositions, for example have the complicated microlitic structure of the porous that can be formed by the coacervate of spraying drying or single particulate (crystal or unsetting), it can form by spraying drying or machinery granulate (being generally mixing/multiviscosisty).
In the method for the invention, the consumption of slurry makes coating on the particle constitute at the most 10% of these particle weights.Yet, preferably, the particulate through applying constitute coating weight at the most 5%, more preferably at the most 3%, 2.5% or 2%, be more preferably at the most 1% or even at the most 0.75% or 0.5%.
